Which git snapshot of Roxen can I run with Pike 8.0 or 8.1?

[Stephen R. van den Berg]

I tried Pike 8.1 and Roxen devel.  That resulted in a problem because
"spider" does not exist anymore in Pike 8.1.

Then I tried Pike 8.0 and Roxen devel.
This resulted in a missing TagSet.eval_finish variable; the variable
is still documented, but is not available anymore.
After working around this, I get:

-:12: Warning: Indexing on illegal type.
-:12: Warning: Got     : multiset(string(49..49)).
-:12: Warning: Index   : string(97..121).

Any suggestions?
I thought I had an older 5.5 version working with Pike 8.0 at the time (say
2 months ago).
